NASA's intrepid Mars rover gets a close-up view of a bizarrely shaped space rock that landed on the lower slope of Mount Sharp.
NASA’s Curiosity rover has detected both methane in Mars’s atmosphere and carbon-bearing organic compounds in its rocks. But it’s unclear where these molecules come from — or whether there’s any biological connection.
Now two years into its exploration of Mars, NASA's big rover has reached the base of the huge mound that scientists hope will reveal the Red Planet's history.
Barely visible water-ice clouds coast across Mars’s skies in new videos from the Curiosity rover.
During two Martian years, Curiosity tracks seasonal patterns in atmosphere, temperature, and maybe even methane.
Samples taken from two drill holes on Mars support the idea that Mars lost a whole lot of water fairly early in its history.
Engineers are looking for a way to continue using Curiosity's drill after a 10-month hiatus, but restoring the drill will probably take several more months.
Curiosity scientists have tracked Gale Crater’s changing environment as it became more, then less, acidic over millions of years. Microbial life could have survived in these conditions.
After four Earth years on the Red Planet, the intrepid rover has found evidence of long-gone water and habitable environments.
Curiosity spotted polygonal shapes on the surface of rocks on Mars — now, analysis of these mud cracks is revealing the history of the long-ago lake that once filled Gale Crater.
Six years from now, there will be a new NASA robot heading to the Red Planet: the Mars 2020 rover. On July 31st mission planners unveiled the rover’s seven scientific instruments, which will pave the way for human exploration of Mars.
As Schiaparelli prepares to land on Mars, how are the other robotic denizens of the Red Planet doing?
